; SHUTTLE FOR WEFT-REPLENISHING MECHANISMS.

This-invention aims to provide anew shuttle for setting in operation electrical mechanisms of the kind stated and isequally applicable to various mechanisms. I he shuttle shown is specially designed I patent, Serial No. 168,171, filed August 4,

1903. In the present applicat on I show is typified in Fig. 1 by released until only the parts of the mechanism immediately adjacent to the shuttle. The entire device is quite simple and cheap and capable of ready a plication to looms already built. The s uttle is especially valuable because it in sures great accuracy in operating only when the thread is exhausted to a predetermined extent. Various other advantages are referred to in detail hereinafter.

An embodiment of the invention is shown in the accompanying drawings. r

I Figure 1 is a horizontal section through a shuttle-box, showing a vation and with the thread exhausted. Fig. 2 is a horizontal section of the shuttle with a full quill of thread in it.

Referring to the drawings, the mechanism a solenoid G, the electric circuit passing through this solenoid and the battery 0 and thence to the shuttle-box or, it may be, to any other suitable 'point on the loom. The present application is concerned only with the devices carried by the shuttle for completing the circuit. I A feature of value in the shuttle is that the means for establishing the connection between the terminals'of the loom are surrounded, at least in part, by the shuttle-thread and are thereby held in inoperative position. Consequently they must be released when the thread is withdrawn, and they cannot be the thread remaining is so short as to yield to the spring which moves the connecting device to its operating position. The connecting device is preferably itself a spring attached at one end to the shuttle-spindle Specification of Letters Ratent.

and free at its other end, th s spring being surrounded in whole or in part by the thread on the spindle.

, Referring again to the drawings, the shuttle Y is provided with means for connecting the two wires L and M, and thus completing the circuit automatically on exhaustion of the shuttle-thread to a predetermined ex- The parts are of such strength that this operation takes place when there is just about enough thread left for another shoot of the shuttle back to the other side of the loom, where it is to be discharged. The shuttle for completing the circuit has a pair of terminals on its outsidethat is, at such points that they may engage corresponding terminals on the inside of the shuttle-box.- The shuttlebox terminals are the ends of the wires L and M.- Means are then provided in the shuttle for establishing a connection between the outside shuttle-terminals referred'to at the proper moment, and thus completing the circuit.

The termin'alson the shuttle-box P may consist of plates Q and R, connected, res ectively, to the ends of the wires L andl M. Similarly-spaced plates S and T on the outside of the shuttle are so spaced that they lie in contact with the plates Q and R, respectively, when the shuttle is inits thrown posishuttle therein in ele-' tion. The usual swell U at the back of the shuttle-box holds the shuttle firmly in this position. The terminal S is connected, as

. shown, to aterminal V on the inside of the shuttle, while the terminal T is connected to the shaft W, which forms the pivot of the spindle X of the shuttle Y. Attached at its outer end to the spindle X is a spring Z, adapted to be surrounded, at least in part, by the thread and constituting a terminal adapted to engage the terminal V when-the, threadof the spindle X is-exhausted. It is understood that the spindle X and its shaft W are of conducting material, so that inthe position of the parts shown in Fig. 1 the circuit is complete. When the slotted quill a, carrying the load of thread I), is placed on the spindle X, the spring-terminal Z is withdrawn and is not released until the thread is substantially exhausted. In case awooden spindle is used the connection of the terminal T with the spring Z may be made by any suitable means, a variety of which will suggest themselves readily to persons skilled in the art. The terminal T may likewise be con- The arran ement of the terminals S, T, and

vV on the wa l of the shuttle with the springterminal Z entirely on the outside of the spindle makes a simple and most reliable device. The necessary movement of the spring to complete the circuit is large and cannot happen accidentally. The construction is also very cheap and can be almost as easily applied to shuttles already in existence as in the making of new shuttles.

Though I have described with great particularity of detail an apparatus embodying my invention, yet it is to be understood that the invention is not limited to the specific structure shown. Various modifications in detail and in the arrangement and combination of the parts may be made by those skilled in the art without departure from the invention.

What I claim is 1. The combination with a shuttle-body, of a pair of terminals on the outside thereof, one connected to the shuttle-spindle, an inside terminal the contact-point of which is .located at the inner side of the shuttle-wall and which is connected to the other outside ter minal, and means for connecting the shuttlespindle with the inside terminal on exhaustion of the shuttle-thread to a pretetermined extent.

2. The combination with a shuttle-body having a pivoted spindle, of a pair of terminals on the outside the shaft of the spindle, an inside terminal 1 the contact-point of which is located at the inner side of the shuttle-wall and which is connected to the other outside terminal, and means for establishing a connection between the inside terminal and the spindle automatically on exhaustion of the shuttle-thread to a predetermined extent.

3. The combination with having a pivoted spindle, of a pair of terminals on the outside thereof, one connected to the shaft of the spindle, an inside terminal the contact-point of which is located at the inner side of the shuttle-wall and which is connected to the other outside terminal, and a spring-terminal on the outside of the spindle and connected thereto and adapted to be released and to make connection with the inside terminal on exhaustion of the shuttlethread to a predetermined extent.

4. The combination with a shuttle, of a shuttle-box, terminals on the outside of the shuttle and on the shuttle-box adapted. to make connection with each other when the shuttle is in the box, one of said outside shuttle-terminals being connected to an inside shuttle-terminal, and the other outside shuttle-terminal to the shuttle-spindle, and a sprin Z attached at one end to the shuttlespindTe, adapted to be surrounded and held inward by thread on the spindle and when released to spring out and contact with said inside terminal.

5. The combination a pair of terminals S thereof, said terminal a shuttlebody with a shuttle-body of and T on the outside T being electrically connected to the sl1uttle-s)i11dle, an inside e of the shuttleconnected to the terminal S, and means for connecting the shuttlespindle to the inside terminal V on exhaustion of the shuttle-thread to a predetermined extent.
